What Is This Tool?
This tool converts pressure measurements from kilogram-force per square meter, a legacy gravitational metric unit, to foot water (60°F) [ftAq], a unit representing hydrostatic pressure by water columns. It helps translate older or regional pressure data into practical low-pressure hydrostatic units used in modern applications.
How to Use This Tool?
-
Enter the pressure value in kilogram-force per square meter
-
Select the input unit as kilogram-force/square meter and output as foot water (60°F) [ftAq]
-
Click convert to obtain the pressure value in foot water (60°F) [ftAq]
Key Features
-
Converts pressure from kilogram-force/square meter to foot water (60°F) [ftAq]
-
Supports legacy and modern unit compatibility for pressure measurements
-
Utilizes a precise conversion factor based on standard temperature and gravity
-
Useful for HVAC, fluid systems, and laboratory pressure analysis
Examples
-
10 kilogram-force per square meter equals approximately 0.03284 foot water (60°F) [ftAq]
-
100 kilogram-force per square meter converts to about 0.3284 foot water (60°F) [ftAq]
Common Use Cases
-
Analyzing low-pressure differentials in HVAC system components like manometers and duct pressure losses
-
Measuring small gas or fluid pressures in regulators and for leak testing
-
Expressing hydraulic head or pressure changes in pumps, water filters, and lab manometers
Tips & Best Practices
-
Confirm units before converting to avoid mixing SI and non-SI pressure values
-
Use the tool to translate historical or regional kgf/m² data into modern hydrostatic pressure units
-
Account for context-specific conditions like temperature and gravity when interpreting foot water pressure
Limitations
-
Conversion assumes standard gravity and water temperature of 60°F; deviations can affect results
-
Kilogram-force per square meter is a non-SI unit requiring caution for integration with SI-based systems
Frequently Asked Questions
-
What does kilogram-force per square meter measure?
-
It is a non-SI unit of pressure representing the force of one kilogram-force applied uniformly over one square meter.
-
Why is foot water (60°F) used as a pressure unit?
-
It represents hydrostatic pressure from a 1-foot column of water at 60°F under standard gravity, useful for low-pressure hydrostatic measurements.
-
Can temperature variations affect the conversion?
-
Yes, since foot water pressure is defined at 60°F, temperature differences can influence the accuracy of the conversion.
